Final answer:
The heat energy required to warm 4.37 g of silver from 25.0°C to 27.5°C is 2.62 J.
Step-by-step explanation:
The formula to calculate the heat involved in raising the temperature of a substance is:
Q = m * c * ΔT
where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
Given that the specific heat of silver is 0.24 J/gº C and the mass is 4.37 g, and the change in temperature is 27.5°C - 25.0°C = 2.5°C, we can substitute these values into the formula:
Q = 4.37 g * 0.24 J/gº C * 2.5°C
Simplifying the equation gives:
Q = 2.62 J
Therefore, the answer is 2.62 J (option b).
